The only difference is that backend prohibits saving the data as it performs restriction evaluation. In the trace we see error

> TypeError: Value of settings:bgpvpn is undefined. Set options.strict to false to allow undefined values.

But this restriction has strict: false! So it seems Nailgun validation must be fixed.
